T STAT CHARLES S.

,E FFQE WINDOW-SHADE FIXTURE.

To all whomr 'it may concern.

De it known that. l, Cuannus S. ticumcuau, of Brooklyn, in the count-y of Kings and State ot' New York, have invented an Improved Article oi Manutacture-viz., an improvement in `i\"'indow-Shade Fixtures; and l do hereby declare that the followingis a full, clear, and exact description of the same, reference being` had to the annexed drawings, making a part oi this specitication, in which- Figure l. is a vertical central sect-ion of 1ny improvement applied to a window. F ig. 2 is a plan or top view of dit-to.

Similar letters of reference indicate corresponding parts in the two figures.

This invention relates to an improvement in the fixtures of window shades or curtains, the kind which are attached to rollers and are adjusted or raised and lowered by the turning oit the saine.

The rollers are turned by means oil cords which pass over pulleys at one end ot the rollers at the upper part of the windows and around pulleys attached to the lower part ot the windows. These lower` pulleys as a general thineY iu the ordinary iixtures cannot be so attached to the window that their axes will be inv the saine plane with the axes ot the upper pulleys but the axes of the two pulleys will be atrightangles with each other and consequently the cords are out ot' line., one side with the other or, they may be said to be in a halt twisted position. The cords in this state or position do not work well, they are liable to run or work oli' the pulleys and it' stretched su'tiiciently tight. to prevent this considerable :triction is created thereby.

The object ot' this invention is to obviate the above objection which object is attained as hereinafter described.

To enable those skilled in the art to t'ully understand and constructI my invention l will proceed to describe it.

I attach the lower pulley A around which the cord B of the shade passes. to the upper end ot a screw rod (l. The pulley is fitted within a socket'. or block (at), and this socket or block is so attached to the end of the screw rod C, that it may turn t'reely around on it, it will therefore be seen that the pulley A is a swivel pulley.

The rod C passes through a nut D which is attached to a plate E. This plate is secured to the lower part and at one side of the window as usual.

I" is the pulley` at one end ot' the roller (l around which pulley the cord B also passes, said roller being at the upper part of the window.

From the above description of parts it. will be seen thaty the pulley A may be turned in any position and consequently its axis will always be in the same plane with that ot the pulley F and the two sides ot the cord 1*) will be in line with each other or in the same plane. The cord may be tightened at any time by turning down the screw rod t, and said rod and the plate E may be covered by any ornamental shell li.

llaving thus described my invention, lf claim and desire to secure by Letters lat.- ent,

As an improved article oit nlal'iutaeture, a wimlow-shade fixture, having); the swivel pulley A attached to the screw rod t which is titted in or passes tl'nfough the nut D on the plate E substantially as herein shown and described ttor the purpose set forth.
